, ,STERIfLIZ G' D E I Application filed March To all whom it mayconcern." i

Be it known that I, THOMAS C; BARRETT, a citizen of the United States,residing at Hartford, in I the county of Hartford and State ofConnecticut, have invented certain new and useful Improvements '-in'SterilizingfDevices,of which the following is a specification. I

v This invention relat'esto' sterilizing devices, "and moreparticularlyto a sterilizer particularly adaptedfor use in connection with the mouthpieces of telephones.

i 3 In the present invention, I provide a casing fadapt'ed'to receive adisinfectant'hold- 1 above thedisinfectantholder ancl*coimni 1nier, jand :furtherprovide a holdena'rranged cating" therewith, the upperholder being adapted to removably s'up'porta sponge "or 1 otherabsorbing medium'shap'ed to fitthe inside of a telephone-mouth piece;

An object of the invention'is' to provide a, vconstruction in; which thesponge may be I this showing: 7

readily separated fromits supporting mem-' ber for the purpose ofcleaning or replacing the sponge. f

A further object is to provide means whereby the disinfectant is alwaysobtainable and at the same time prevent evaporation of it.

In the accompanying drawings, I have shown one embodiment of theinvention. In

Figure 1 is a central vertical sectional view, I Figure '2 is ahorizontal sectional online 22 of Figure 1,

Figure 3 is a perspective view of a cover view or supporting membertowhich the sponge able material and of approximately the same shape asthe telephone mouth iece, is arranged within the casing. Th1s holder isprovided'with an extension 5 at the bottom, adapted to be receivedwithin the neck of 20, 1925; semi uo. 17,05 s;

bulb and provided with a passage 6 through which the disinfectantjmayflow; I V A sponge 7 (see Figure 5) is adapted to'be,

arranged within the holder and this sponge is provided withan upperflangel8q 'A'supaorting member 9 of suitablyrigid material is secured tothe flange of the sponge and is'provided with a; handle}10, by'means ofwhich the sponge may be reinoved fro'inthe holder, when desired. As"sh0w1 1,-'this sup-v po'rting'inember is provided with 'a periph er'al'fla'nge 11, having-spaced projections} 12. A rim 13 is adapted to -bearrangedlon V H 1 the under sideof the flange: or spo n'ge (seeFigure-'1) and this rim is pro videdi with @11 out portions or-{recess'es' lfiusimilarftin f shape tothe projections zl2"'a'nd:-similarly spacedbn the-rimxgi l heqrimis furtherpro I i vided withanupstruckportiony15 to: permit it to" be rotated to: bring theprojections 12 and recesses l t-out" ofalinementf;(see Figure 2) L1 Theouter casing inlay a be provided w'it11 a suitablelivcoversllfi. which,asashown, I a

maybe hinged to the casing. p is In operation, the rim '13fis' passedover the smaller end of the sponge and arranged beneath the flange.'Thesupporting member 9is thenpassed over the top of the sponge and theprojections 12,passed over 7 the recesses 14 in the rim. The rim is thenturned by engaging the upstruckiportion l5 to'bring the recesses andprojections out of alinementu The sponge is then placed in the holdervand when it is to be used, jpres sureis appliedto the handle 10etodepress the upper holder 4 and force-'Ethe disinfectant through thepassage-6 to the sponge.

The sponge isthen removed and the interior I .95 cleaned and sterilizedby placingthespon'ge 7 of thelmouth piece of the telephonemay, be

within itand rotating it* slightly to apply- 7 the disinfectant thereto.

The sponge may 7 i .be readil removed from thesupporting member orthepurposeof cleaning it or replacing it. The bulb 2'may bev refilled withdisinfectant by depressing it and pour ing the disinfectant'throughtheupper hold-' er. It will be apparent that the supporting.

member 9 also serves'as a cover to prevent the" disinfectant frompassing upwardly through the sponge and evaporating.

It is to be understood thattheform of my invention herewith shown anddescribed 1 is to be taken as a preferred example of the same,and thatvarious changes in the shape,

no f

,size,'and arrangement of parts may be resortec'l' to Withoutdepartingfrom the spirit of the invention or the scope of the subjoined claims.

Iclaim:
